DISTRIBUTING BUCKET FUR CONCRETE-PAVING MACHINES.

Application filed June 15, 1921.

To all whom it may concern:

Be it known that I, JOHN P. FABER, a citizen of the United States, and a resident of the borough of Dunellen, in the county of Middlesex, State of New Jersey, have invented certain new and useful Improvements in Distributing Buckets for Concrete- Paving Machines, of which the following is a specification.

The improvements relate to dumping buckets, and particularly to buckets of this character designed to form a part of an apparatus for mixing and distributing concrete for road paving and other work. In devices of this kind it is desirable for various reasons to have the bucket provided with dumping doors at its bottom extending crosswise of the line of travel, the said doors opening outwardly and downwardly when the bucket is dumped. This causes them to come in contact with the heat of materials deposited by the bucket, and sometimes with other objects when the bucket is moved and makes it desirable that the said doors be arranged to swing upwardly so as to ride over such obstacles without injury thereto or to any other part. Th doors should also have independent movement so that when one comes in contact with an obstacle it can move to pass thereover without detrimentally affecting the other or the connection between them or the door-operating means. It is to provide for this that the present improvements are primarily designed.

The improvements are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a dumping bucket, with doors at the bottom thereof embodyin the improvements, and of the carriage anc. door-operating means; Figure 2 is a plan of the bucket of Figure 1; Figure 3 is a medial vertical section taken substantially at right angles to the line of travel of the bucket showing the doors in open position, and also showing adjacent parts.

The construction illustrated in'the drawings is a specimen embodiment of the improvements, and shows the best form in which they have been embodied, but it is apparent that other forms may be used and that the details of construction may be varied without departing from the scope of the invention.

Serial No. 477,631.

The bucket 1 may be of any suitable shape, and is mounted on a carriage 2 traveling to and from the mixing machine on the boom 3, by means of the rollers 4:. A trip and restoring mechanism for the dumping door in the bottom of the bucket is provided in the links 5, 6, and 7 operated by the trip-arm 8, which is moved to close the doors when it comes in contact with the member 9 on the boom on its return to the concrete mixing machine. Its bucket dumping movement may be accomplished by any suitable mechanism or by hand.

The doors 10 are hinged to the bottom of the bucket 1 at 11, and extend across-the bucket. from side to side, at right angles to its line of travel along the boom, and are adapted to be closed by means of the link 5, operated in the manner described. This link has a sheave 12 mounted on its lower end, and each door has an eye 13 secured toits inner and upper side near its outer edge. Connected at its two ends with the eyes 13 and running over the sheave 12 is a chain 1 1, by which the doors are connected with the closing mechanism in such a manner asto permit lateral movement while they are in open position. The length of this chain is approximately equal to twice the distance from the sheave 12 to the connecting eye of either door when the door is closed, and as the chain travels freely over the sheave 12 the doors may swing laterally when in open position, but without changing their mean distance from the operating link. The result of this construction is that while the doors may swing freely in one direction or the other to pass over the heap of materials dumped by the bucket, or any other obstacle (see dotted lines Fig. 3), they will be tightly closed and securely held when the operating mechanism is moved to closing position. This permits the disposition of the doors crosswise of the bucket, and also enables the doors to act as spreaders for the material dumped therefrom, the return movement of the bucket causing them to pass through or over the top of the material in this last operation. If the forward door strikes an obstacle it will swing up thus slacking the chain 14, and if the rearward door strikes mitted by the slack of the chain to swing backward and upward. As the link in permitting the doors to open moves downward a suflicient distance to allow the door to depend vertically from the bottom of the bucket, the length of chain is sufficient to permit both doors to assume a substantially horizontal position, if necessary, while passing over the dumped concrete or any other obstacle while, at the same time, no matter What the position of the doors may be when the restoring mechanism operates they will be closed instantly, and securely held in closed position until the drunping mechanism is again tripped.
